ICERA Group's Cadence One Toilet

This is a sleek gravity-fed toilet that uses only 1 gallon of water per flush. Features include a fully glazed 2-1/8-inch trap and a glazed non-staining, antimicrobial surface that the manufacturer says keeps the bowl cleaner. The WaterSense-certified product is available in white, bisque, and black, and also in a model that uses 1.28 gallons of water per flush. 855.444.2372; icerausa.com.
